Loving my '04 IS200, but have a couple of small niggles that I could do with some advice/direction on, please.
Firstly, it seems that I need to top up the expansion tank about every two weeks, is this normal? When I bought the car I had the cam belt changed, and the water pump replaced at the same time. No puddles underneath when sat, even for a couple of days, no evidence of ingestion into the engine, and no steam when warm from the engine bay. Any ideas?
Secondly, after driving for a while, and lots of gear changes, on pulling away I can hear a rhythmic squeaky rubbing noise, like something in the clutch is rubbing or not engaging evenly. It only happens on the initial pull away, car pulls away smoothly as usual, even if I pull away in second (for diagnostic purposes), and only if there has been lots of stop/starts. If i do sixty odd miles on the motorway, there's no noise when pulling away afterwards. There does seem to be a vibration felt through the steering wheel when driving in the sixty to eighty mph speed range. Whether this is related or not I have no idea? Again, any direction as to the cause would be greatly appreciated.
